By default, svnlook diff will treat
copied files very much like any other added file,
displaying in their entirety the contents of the new file
and merely using a different label to draw the copy/add
distinction. However, you can use the
--diff-copy-from option to cause
svnlook diff to consider a copied
file as worthy of mention only if it differs from the file
from which it was copied, and to actually describe those
differences.
